[PATCH v4 05/10] PCI: brcmstb: Expand inbound window size up to 64GB

[Stanimir Varbanov]

BCM2712 memory map can support up to 64GB of system memory, thus expand
the inbound window size in calculation helper function.

The change is save for the currently supported SoCs that has smaller
inbound window sizes.
